Derby City Council’s hygiene inspectors have not said why the businesses scored zero.

No-one from the restaurant was available for comment.

The national Food Hygiene Rating Scheme features inspections carried out by councils.

Businesses are rated on a scale ranging from zero – which means “urgent improvement necessary” – to a top rating of five, or “very good”.

With Christmas only four weeks away, Derby City Council is urging people to make sure they consider a restaurant’s hygiene score as well as its menu.

The council is advising residents to choose eateries with a rating of three or more, which applies to 92% of food businesses in Derby.

Councillor Asaf Afzal, cabinet member for planning, environment and public protection, said: “At this time of year, lots of people are busy arranging gatherings at restaurants, cafés and pubs to celebrate the festive season.

“Before they book, we’d like to encourage people to think about a venue’s food hygiene rating as well as its menu and ambience, so that they have a safe and pleasant experience.

“Here in Derby we have a good standard of food hygiene in our eateries, and the Food Hygiene Rating Scheme makes it easy to find out exactly how a restaurant, café or pub has been rated. Look for the rating on the door, ask a member of staff or visit www.food.gov.uk/ratings.”

Hygiene ratings can be found by looking for the green and black food hygiene rating stickers displayed on windows and doors. If a sticker is not visible, you can ask staff or to check online at www.food.gov.uk/ratings. They are also online at www.food.gov.uk/ratings.
